VoIP Phone Systems
Voice over Internet Protocol (VoIP) represents the future of business communications. Our VoIP business telephone systems deliver enterprise features at affordable prices while providing flexibility that traditional phone lines cannot match.

Cloud-Based Communication
Cloud VoIP systems eliminate the need for expensive on-site equipment and maintenance. Your telephone systems for business operate through secure internet connections, allowing employees to make and receive calls from anywhere. We configure hosted PBX solutions that include auto-attendants, call routing, voicemail-to-email, and call recording. System updates and new features deploy automatically without disrupting operations.
Cost Savings and Scalability
VoIP business telephone systems dramatically reduce communication costs compared to traditional phone lines. Long-distance and international calls cost significantly less, and adding new lines requires no additional hardware installation. Our solutions scale effortlessly—add or remove users instantly through web portals. This flexibility makes VoIP ideal for growing businesses and companies with seasonal staffing changes.
Advanced Features
Modern VoIP platforms include features once available only to large enterprises. Call forwarding rules route calls based on time of day, caller ID, or employee availability. Conference calling supports dozens of participants. Mobile apps transform smartphones into office extensions. Integration with Microsoft Teams, Slack, and other collaboration tools creates unified communication environments where voice, video, and messaging work seamlessly together.
Small Business Solutions
Telephone systems small business installations require solutions that balance functionality with budget constraints. We design affordable systems that deliver professional communication capabilities without enterprise complexity.

Essential Business Features
Our telephone systems small business packages include everything needed for professional operations. Multi-line support handles multiple simultaneous calls. Auto-attendant greets callers and directs them to appropriate departments. Voicemail boxes for each employee with email notification. Call transfer, hold music, and intercom functionality. We configure systems that present a professional image while remaining simple enough for any employee to operate.
Flexible Installation Options
Small businesses can choose between cloud-based systems requiring minimal hardware or traditional on-premise systems with desk phones. We recommend solutions based on your internet reliability, budget, and specific requirements. For businesses with 5-50 employees, cloud systems often provide the best value with lower upfront costs and predictable monthly expenses. Companies requiring maximum call quality control may prefer on-premise systems.
Growth-Ready Infrastructure
The best business telephone systems for small companies accommodate future expansion without expensive replacements. We design infrastructure that supports adding locations, remote workers, and new features as your business grows. Start with basic functionality and activate advanced features like call analytics, CRM integration, or video conferencing when needed.
Enterprise Communication Systems

Our enterprise solutions connect offices across multiple locations into unified communication systems. Employees dial extensions to reach colleagues anywhere in your organization. Central administration manages all locations from single interfaces. We configure call routing that directs customers to appropriate offices based on location, department, or expertise. Disaster recovery features ensure business continuity by rerouting calls if locations experience outages.
Advanced Call Management
Enterprise business telephone systems include sophisticated call handling capabilities. Automatic call distribution (ACD) queues manage high call volumes and distribute calls to available agents. Skills-based routing directs calls to employees with specific expertise. Real-time dashboards display queue status, wait times, and agent availability. Supervisors monitor calls, provide coaching, and generate performance reports.
Integration and Analytics
We integrate telephone systems for business with CRM platforms like Salesforce, Microsoft Dynamics, and HubSpot. Screen pops display customer information automatically when calls connect. Call logging records all interactions in customer records. Analytics track call volumes, response times, abandonment rates, and other metrics that inform business decisions. This data helps optimize staffing, improve customer service, and identify training opportunities.

Unified Communications
Modern business telephone systems integrate voice, video, messaging, and collaboration tools into single platforms. Employees switch seamlessly between phone calls, video meetings, instant messaging, and email. Presence indicators show colleague availability in real-time. Screen sharing and document collaboration happen during calls. These unified communications platforms reduce the need for multiple applications and create more efficient workflows.

Mobile applications provide full desk phone functionality on smartphones—make and receive calls using business numbers, access voicemail, check presence status, and participate in conferences.

I am a property manager in Manhattan and had to find a company to repair a busted intercom system. I came across Lock and Tech, and George set everything up for me, answered all of my questions over three different conversations, and he never made me feel like I was bothering him with all my questions and concerns. The technicians did a fabulous job and had the intercom fixed in less than an hour. The men cleaned up thoroughly after the job which I completely appreciated. I highly recommend this company and will definitely use them again.

We are renovating our small (6 unit) apartment building in Manhattan and decided it was time to replace our very old and finicky intercom. We opportunistically decided to install a Virtual Doorman so we buzz deliveries in when we are not at home. The team at Lock and Tech has been great. The installation was all done in one day and we all have electronic keyfobs that control our first two doors, in addition to the keypad. The team is very responsive and professional. I highly recommend them!

After doing research for a an installer, we landed with Lock & Tech for a small install. I was so impressed with their customer service, quality and overall work, we hired them for a larger job. We’ve like the work so much we’ve been using them for the past 3-4 years doing installs in and around our facility. The team is very knowledgeable and accommodating, and will work with you throughout the whole process until you are satisfied. Prices and services are great and will continue to use their services in the years to come. Highly recommend!

I selected Lock & Tech for our intercom system installation after looking up every company that does this work. Even after selecting them I was skeptical of Google and Yelp reviews and wasn’t sure what I would get. It turns out they are reliable, do expert work, and are great to work with. My building is very old and they did an excellent job of installing the intercom, strikers and locks despite the difficulties that exist in old buildings. They were attentive to all our particular needs and responded quickly to calls or texts. Above all, the price was very reasonable, more so than other installers. I highly recommend them.

We had Lock and Tech USA install a security camera system to our Prospect Heights co-op and Gabriel and his team did an amazing job! They installed the whole system, including 6 cameras on the interior and exterior of our building in one day! The quality of the cameras and equipment is top of the line- the picture is crystal clear. They are very thorough, responsive, professional and offer high quality installation and equipment for a great price. They email and call when you need and made sure we were 110% happy with everything. Highly highly recommend these guys!

Derek was amazing and professional. He met all my needs and answered all my questions. His workers came knowing what was needed to be done and did an amazing job. I needed to get my camera system replaced with a new one. They charge on a hourly basis, so the workers did not take their sweet time to run up the price. They did a very professional job at a very fast rate. I am very pleased with Lock and Tech USA. I will always refer to them for any security needs. Thank you guys.

Lock and Tech USA successfully installed an AIPHONE intercom system at my Brooklyn office. Their technician, Viktor, was personable, pleasant, and highly skilled. Viktor carefully installed the intercom system without damaging expensive suede wallpaper, professionally concealed wires in walls, and ensured that the intercom system was perfectly functioning before departing. Viktor is a wonderful technician. As such, I recommend Lock and Tech for AIPHONE intercom installations – Ask for Viktor!

Great communication, follow-up, and support!! Sales was straight forward, no point even negotiating, very reasonable and understanding! Installation was quick and thorough and they put everything exactly where I wanted them to be. We had an issue with one of the devices and they responded in minutes and even came back the next day. Amazing service!
